Hello,

I've recently purchased Genuine Ross-Tech VCDS HEX-V2 interface from Gendan, I've not had chance to test or use it yet! However, I've just had to buy a new key for my grandmothers 2007 VW Polo after she lost her keys, I purchased a genuine key from TPS so I presume it comes part programmed? Will I need the VCDS to programme the key to the car and is it straight forward? (she lives a 2 hour drive away so I want to make sure I will be able to do it!)

Thanks!

Unlikely.

Even a properly "pre-programmed" key still needs to be matched to the car, and 2007 on generally uses a challenge/response mechanism where the challenge changes with every ignition cycle and only the mothership's servers know how to generate the requiset response from the challenge. On the off chance that the 2007 Polo does not yet use this scheme, you would still need a security code ("PIN") to match the key.

VCDS should allow you to match the Keyfob Remote signals to the car - for central locking buttons on the remote.

As Uwe described, to match the key to the immobiliser (to allow the Engine to start), you will need to get this done at a dealer or get access to the 7-digit SKC (Secret Key Code) for the car. This link explains in more detail:

we don't know what car we are talking about here. I took for granted that VCDS CANNOT teach keyfobs. if it did, I would really like to know how, on MQB cars.

The OP specifically mentioned a 2007 VW Polo. ;)

Every MQB we've had in our fleet has had Kessy, and those are definitely no-go, but I'm not sure about keyfobs on non-Kessy cars like yours.

Hi,
I'm interested in this and want to try to add new key to IMMO 4 AUDI A3 2004. If I understand good enough how vcds works, with vcds is possibile to programm and match new key to immo if I have pin for security access?
I read this guide:

I think it is possible on that car if the cluster and ECU are properly matched to begin with and you have the immobilizer PIN code (which might be 5 digits, not just 4). However, there may also be some pre-matching of the transponder necessary? I'm not sure. Maybe @Jetta 97 knows more?

If your willing to invest and have a go, Super VAG + CAN diagnostics might help you out! I bought one a few years back when I was working on a Transporter that the customer had not got the security details of. The Super VAG + CAN will read the ECU codes that are in them but will not program codes back in. Therefore if you have both Super VAG + CAN and VCDS you MIGHT be in with a chance!

Uwe,
Correct , VCDS can program key on this car if you have SKC(Pin) and key is precode to car .

So, it isn't enough to have new clear key and IMMO PIN. I must precode key with odis or other key programming tool like AVDI?
